The INSPIRE Summer School 2023 "Cardiovascular Safety Pharmacology and Cardio-Oncology" was held in Antwerp from 24 to 30 August 2023. It consisted of theoretical lectures complemented by hands-on sessions in associated technologies. This course was a continuation of the EU-funded collaborative training network in safety pharmacology INSPIRE, which in the past three years had built a training program benefiting from the academic, industrial, and clinical perspectives by exploring the latest technological capabilities to address emerging cardiovascular and cardio-oncology safety concerns.
